Abstract

The utility model relates to a mantellum anti explosion glass bottle, belonging to the invention of increasing the strength and improving the use safety of the glass bottle. Recently the complaints of beer bottle and pressurized bottle explosion and injuring the human are usually saw in the newspaper. In order to eliminate the harm, tightly buffering a layer of plastic film over the outer surface of the glass bottle is feasible. After the film is being set, the friction of the glass surface is eliminated, the collision is buffered, the micro-crack and the crack enlarging can not generate on the surface of the glass easily, so the explosion is uneasily to happen, even the explosion happens, the film can involve the cullet tablets from flying apart or can decrease the flying apart speed greatly depending on the hardiness of the film, thus the safe of the drinker is guaranteed.

Description

Mantle implosion guard bottle

The utility model is a kind of about overlap film-coating on the glass bottle outside face, with intensity that increases glass bottle and the invention that improves safety in utilization.

Existing glass bottle is in packing, carrying, pouring process, because of friction, collision cause bottle surface to produce the invisible tiny crack of countless naked eyes.Crackle progressively enlarges, and produces the stress concentration phenomenon, and then bursts suddenly, causes personal injury and property damage.Only be example with the beer bottle, annual to cause the complaint amount of personal injury just to reach tens of because of blast, though add damage and do not complain and exploded and do not caused personal injury, estimate at thousands of ancestors, be called by medium " beer bomb ".In order to protect customer's interests, country has issued the compulsory standard of beer bottle, pop bottle in recent years: GB45 ＇/4-96 " beer bottle " and QB2142-95 " soda glass bottle ".But, be example only with current required standard " beer bottle ", new standard except the physical and chemical index of bottle artificial improve and quantification, not having not take effective measures from aspects such as shape, structures increases its safety, so the quality of bottle itself is not significantly improved.A small amount of bottle that overlaps film-coating on bottleneck or body is also arranged in the market, but just be used for sealing bottleneck or manifest decorative effect as the trade mark carrier; The toughness extreme difference.Along with the increase of beverage consumption amount, increase with the bottle amount is also anxious.Alleviate and even to eliminate the harm of glass bottle blast imperative.

The purpose of this utility model is to improve the quality of glass bottle, with plan safety, allows it be difficult for blast.Even blast, its " lethality " also can weaken even disappear.

For achieving the above object, the utility model adopts the method at glass bottle outside face cover film-coating that the outside face of glass bottle is covered, and makes it to be isolated from the outside.So just can effectively eliminate the friction of bottle surface, damp impacts has destroyed the condition that produces tiny crack, from the blast of source prevention glass bottle; Meanwhile, even because of improper use, allow glass bottle produce and collide and burst, its tough and tensile film-coating also can allow chunk glass be involved, and maybe can not fly out, or the speed that flies out reduces greatly.So just guaranteed the safe handling of glass bottle.

The method of cover film-coating is to be coated with full glass bottle outside face with plastics liquid, and drying is solidified the back and formed the Global Macros film of being close to bottle naturally.Also can adopt according to the variation of bottle diameter and segmentation puts the heat-shrinkable film circle, pass through Oven heating again, make the film circle be subjected to thermal contraction, and become one with bottle.

This programme only need overlap the thin film clothing at the glass bottle outside face, thereby simple in structure, and technology realizes that easily cost is low; From the cover film-coating intuitive analysis as can be known, it can improve the total quality and the safety in utilization of glass bottle.

Concrete structure of the present utility model is provided by following two kinds of embodiment and accompanying drawing.

Embodiment one is achieved in that as shown in Figure 1, at surperficial full coat one deck plastics liquid of glass bottle 1, treats to form one complete film protective clothing 1 ' naturally after its drying is solidified.

Embodiment second be according to bottle on short transverse the diameter difference and the heat-shrinkable film lasso is made in segmentation in advance, then with lasso segmentation cage on bottle, send into Oven heating, lasso is because of being subjected to the thermal contraction lock ring in bottle surface.As shown in Figure 2, film Fig. 2 ' of cylindrical shape is enclosed within on the body 2, and the film circle 3 ' of circular conical surface shape is enclosed within on the shoulder 3, and the back cut diameter of film circle 3 ' should be identical with the shoulder diameter on this height, and it just is unlikely because of gravity and falls down.Coat film 4 ' then directly brushing plastics liquid and may extend to bottleneck 5 in bottleneck 4 places.Three sections films are answered overlapping overlap joint, bottle could be protected complete.The heat-shrinkable film lasso should be bigger slightly than bottle diameter, just is convenient to suit.The direction that the shrinkage percentage of lasso is big should be positioned at the circumferencial direction of bottle, so that the banding body; The direction that shrinkage percentage is little should be positioned at the short transverse of bottle, in order to avoid contraction is too big, forms the exposed glass of unprotect film, causes the weak link of potential safety hazard.

Claims

1, glass bottle of the present utility model is characterized in that going up cover thin film clothing (1 ') at the outside face (1) of simple glass bottle.

2, glass bottle according to claim 1 is characterized in that the outside face (1) at glass bottle directly is coated with one deck plastics liquid, and dry back forms monolithic film membrane cover (1 ') naturally.

3, glass bottle according to claim 1 is characterized in that the body (2) at glass bottle is gone up the heat-shrinkable film circle (2 ') that overlaps one deck cylindrical shape.

4, glass bottle according to claim 1 is characterized in that the shoulder (3) at glass bottle is gone up the heat-shrinkable film circle (3 ') that overlaps one deck circular conical surface shape.

5, glass bottle according to claim 1 is characterized in that bottleneck (4) and the bottleneck (5) at glass bottle gone up brush one deck plastics liquid, and dry back forms coat film (4 ').

6, according to claim 1,3,4 or 5 described glass bottles, it is characterized in that cylindrical film circle (2 '), the overlapping staggered overlap joint of the coat film (4 ') of conical film circle (3 ') and bottleneck bottleneck, the shelves of not leaving a blank.
